Notes on Color Theory

The name of a color. There are two classes:
1. Primary (i.e., blue, red, yellow).
2. Secondary (green, orange, violet)

value:

The amount of light reflected by a hue; the greater the light
reflected, the higher the value.

saturation:

The purity of a hue; the higher the saturation, the purer the
hue. Value and saturation are not constantly related: high saturation yellow
has a high value (reflectivity); high saturation violet has a low value.
Also called intensity.

complementary colors:

Pairs of colors, such as red and green, that together embrace the entire
spectrum. The complement of one of the 3 primary colors is a mixture of
the other two.
-- red/green -- blue/orange -- yellow/violet

Methods of Producing Color:

Subtractive Mixture

pigments

Additive Mixture

lights

Combination of diferent pigments:

a) on the palette
b) on the canvas.

Mostly primary colors used; if any pair of complementaries are mixed,
produces black. Mixture of all 3 primaries produces black.
